 ** Experimental and for linux pros only **
-Here is how to setup the Raspberry Pi to support normal OpenGL (with acceleration) and be able to compile the Proton SDK examples.  It's actually also possible to set things up for GLES, but this is probably easier these days.  (tested with Raspbian "Jessie" on 6/18/2016)
+Here is how to setup the Raspberry Pi to support normal OpenGL or GLES (both with acceleration) and be able to compile the Proton SDK examples.   (tested with Raspbian "Jessie" on 6/18/2016)
+From my tests I got it working two ways:
+.  Set it up using the OpenGL experimental driver.  Result: Proton examples only work in X11 in windows mode.  Fullscreen (using the SDL2 harness) didn't work.  [[proton:raspi_opengl_setup|Directions to setup]]
+.  Set it up using GL ES, won't work in X11, works full screen by starting from console.  This is more useful for me as it's more pedal to the metal and easier to get 60 fps, no x overhead.  With this method we're setting up our own EGL context manually, but still using the SDL2 harness for other things
+** Instructions to setup GLES with Raspberry Pi and run Proton SDK examples **
 These steps are what I use to compile stuff by copying things from my Windows computer.  A normal user would probably just grab the svn tree and run .sh files.
-  * Give the video card more memory on the pi.  Run raspi-config and give it 128 or 256 (good for the pi3)
+  * Give the video card more memory on the pi.  Run raspi-config and give it at least 128 or so to be safe.
-  * Also enable the experimental OpenGL driver under the Advanced section in raspi-config
   * Install cmake on the pi (sudo apt-get install cmake)
   * Do "sudo rpi-update" to make sure your firmware is updated

-You'll have to the copy the RTBareBones/bin/interface dir to /RTBareBones/linux as that has font/graphics needed.
+The last step of the build copies the rtbarebones binary to /RTBareBones/bin (as that's where the media is), so go to that dir and run "./rtbarebones" and it should work.
-Running "./rtbarebones" from the RTBareBones/linux dir should now work.
+RTSimpleApp is much the same, although you'll need SDL2's mixer as well.  Unlike with the base SDL2, we can just grab a pre-compiled one like this:
+<code>
+sudo apt-get libsdl2-mixer-dev
+</code>
+And that should compile ok. We don't have a mouse or anything but I can see it's running at 60 fps...
-That should be enough to get you going.
